About

Crystal PvP has become a pretty popular combat mode in Minecraft. Crystals
themselves were never designed to be used in combat. Because of this, a client
ping (latency) plays a significant role in a crystal PvP fight, affecting how
fast you can spam. This mod helps to reduce (but does NOT fully remove) the ping
factor from crystal PvP fights. This is commonly called a client-side crystal
optimizer
mod. It also removes the ping factor for PvP with anchors, though
the ping doesn't play a big role in anchor fights, and it might even be
beneficial to have high ping in these fights. This is not the only crystal
optimizer mod available, but it's the most configurable out there.

Note: A server-side crystal optimizer plugin (not this mod) is much more
effective. Consider checking the /fastcrystals command or similar commands
on your server. Ask the admins to install one if the command doesn't exist.

Frequently Asked Questions

HCsCR server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.10). You can switch loaders with one click in the panel.

Is HCsCR compatible with fabric and forge and neoforge?

HCsCR officially supports fabric, forge, neoforge for Minecraft 1.21.10, 1.21.8, 1.21.5. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with HCsCR – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if HCsCR consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
